ArmPkg/ArmMmuLib: Fix implicit cast

Browse Source 
While building with the following command line:

 build -b DEBUG -a AARCH64 -t VS2017 -p MdeModulePkg\MdeModulePkg.dsc

A missing cast triggers the following warning, then triggering an error:

  ArmPkg/Library/ArmMmuLib/AArch64/ArmMmuLibCore.c(652):
  warning C4152: nonstandard extension, function/data pointer
  conversion in expression

This patch first casts the function pointer to (UINTN), then to (VOID *),
followowing the C99 standard s6.3.2.3 "Pointer", paragraphs 5 and 6.
This suppresses the warning.
